Channel tunnel train operator Eurostar has reported that its sales revenues have increased by 7% to £227m for the first quarter (Q1) of 2014, compared with £213m for the same period in 2013.
The company’s passenger traffic increased to 2.3 million, compared with 2.2 million in the previous year.
Eurostar chief executive Nicolas Petrovic said: "The improvement we have seen in the corporate travel market in recent months underpins the strong performance reported today.
"Coupled with the benign winter weather, which saw far lower levels of weather-related disruption than in previous years, the first quarter has set us on course for continued growth throughout the year. "
The growing economic confidence has driven stronger business travel bookings on both sides of the English channel.
Eurostar noted that leisure ticket sales have also continued to grow throughout Q1 with passenger volumes up by 3% on the previous year.
The operator has also opened first phases of its new ticket office in St Pancras International, while current final phase work will be completed by the end of May.
Shifted to an existing check-in area within the station, the new ticket office can accommodate leisure and Business Premier passengers.
Petrovic added: "Our ongoing programme of investment spans every area of our business, from our fleet of trains to the stations where they operate."
